Paper Abstract

This contribution deals with the problem of determination of basic parameters of unknown lenses, namely their radii of curvature, thicknesses and refractive indices of materials (e.g. optical glasses) from which these lenses are made. The aim of this work is to present and analyze a method for the determination of internal parameters of unknown lenses, namely index of refraction and Abbe number. The method is proposed to obtain these parameters and mathematical relationships are derived that allow us to determine the refractive index and Abbe number of lens material based on the measured radius values, the thickness and the position of the focal point or the focal length. It is also performed an uncertainty analysis of the proposed method.
